Limited username

my name is yiazmat on replaypoker but the username forbid us to make a long username.
actually i want to be yiazmat50112254 on replaypoker because the name yiazmat could have been chosen by more people and yiazmat50112254 is really me.

so my question is if you agree the username should be possible to be longer then post it, maybe with lots of votes they can do something about it.

ty for the coming posts.
